title: Surgical repair of a complete endocardial cushion defect in a dog.
abstract: OBJECTIVE
  To describe surgical repair of a complete endocardial cushion defect (ECD) in a dog.
  
  
  METHODS
  Clinical report.
  
  
  METHODS
  A 5-month-old, 9.2 kg male Shetland sheepdog.
  
  
  METHODS
  Echocardiographic examination revealed an ostium primum atrial septal defect (ASD), an inlet ventricular septal defect (VSD), mitral regurgitation (MR) and tricuspid regurgitation (TR), and a complete ECD was diagnosed. Surgical correction was performed using cardiopulmonary bypass (CPB) via right atriotomy. A polytetrafluoroethylene (PTFE) patch was secured along the margin of the inlet VSD using simple continuous suture, then the cleft in the septal mitral leaflet was sutured. Similarly, the cleft in the septal tricuspid leaflets was sutured. To complete inlet VSD closure, the VSD patch was secured to these sutured leaflets by simple continuous suture. Another PTFE patch was used to close the ostium primum ASD.
  
  
  RESULTS
  After surgery, MR, TR, and interventricular shunting were decreased. The dog was alive 6 years and 5 months after the surgery with no evidence of an interventricular shunt, TR, or other clinical signs.
  
  
  CONCLUSIONS
  Complete ECD in a dog was corrected using a 2-patch technique under CPB.
